Why not just say "we'll do whatever the frack we want, so long as there's no law against it?"
Can you enter into a valid contract that says one of the parties to it *will* violate some law? What would that even mean? Okay, okay, I'll Google it myself -- no, such contracts are not enforceable. Which makes it all the more absurd to construct a contract that spends many pages listing things they will or won't do, when it also says they may do *anything* that's legally permitted.
